Tx
Repeated episodes of rheumatic fever can worsen valvular function. Therefore it is recommended that patients with a prior episode of rheumatic fever be given antibiotic prophylaxis with penicillin to prevent a recurrence. The duration of treatment is not firmly established, but most physicians will treat until the patient reaches the age of 18.
Patients who have had an episode of rheumatic fever should receive antibiotic prophylaxis with penicillin to prevent further attacks
Complications
